Another question I have is how far do I need to be away from the corners, and top of the tank. I guess the top would just be where I want the waterline, but is there a distance that I need to be from the corners for strength/stress reasons? If I can find a press, and bit I think I'm going to try and do it myself. I'd hate to locate the holes in such a way that my tank would not be safe, or could break for some reason. Any tips here?


Dan, thanks for the advice on the bulkhead size.
